Not, it is shown that along the axial, cross-sectional view of side of the axis of symmetry of the winding of electromagnetic equipment.
According to this example, the layer thickness of the cable of structure winding is 300 μm.For in Fig. 4 a-c
The low-voltage winding LV in the left side of each figure for simple and there are three circle/dishes, and
For the high voltage winding HV on the right side of each figure in Fig. 4 a-c then for simply having
Four circle/dishes, use the cable of CTC type.Three width figures do not illustrate wire harness.As institute
It can be seen that, by increasing the relative permeability that winding cable includes the layer of magnetic material
μ r, the magnetic field in cable decreases, and therefore loss decreases.
Fig. 5 shows the leakage inductance of every winding dish of the pcrmeability function being plotted as layer,
The quantity of the dish during wherein N is winding model.Energy due to the magnetization of layer and the bending of field and
Increase with pcrmeability, and therefore inductance increases.To be noted, N=Inf represents
Wherein have ignored the model of end effect, and to describe wherein flux directions be axial dish
Situation.D represents the thickness of layer.
Fig. 6 shows and is plotted as the relative magnetic permeability of layer for the different numerical value of layer thickness
The total losses of the often dish of rate function.The conductivity of coating is assumed to be 1*105S/m and loading
Electric current is 1A.
